The language beneath the language

Scholar-level Latin

J.R.R. Tolkien was an Oxford philologist who drew deeply on Latin when creating Quenya and the languages of Middle-earth. He called his love of inventing languages "a secret vice." Lexis Arcana's 450+ roots cover the vocabulary of a classical scholar — organized into 16 thematic categories that mirror the great themes of literature.
